BRUSH FOR BOLTING-MACHINES.

Application filed August 4;, 1914.

To all whom it may concern:

Be it known that we, NEWTON M. Burrs and CHARLES L. HAwonrr-r, citizens of the United States, residing at Wilmington, in the county of Clinton and State of Ohio, have invented certain new and useful Tmprovements in Brushes for Bolting-Machines, of which the following is a specification.

This invention relates to bolting machines of the reciprocatory type and has for its object to provide a brush suitably supported in operative position against the under side of the bolting cloth and automatically operated by the reciprocation of the bolting machine.

Another object is the provision of a longitudinally slidable brush holder and means for controlling the direction of the movement of the holder.

With these and other objects in view, the invention consists in the novel construction, arrangement and combination of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which,

Figure 1 represents a longitudinal sectional view through a bolting machine of the ordinary construction, showing the application of our automatic brush, Fig. 2 represents a view similar to Fig. 1 showing the brush holder in a different position, Fig. 3 represents a vertical sectional view through the bolting machine and brushing apparatus, taken at right angles to Figs. 1 and 2, and, Fig. 4: represents a perspective view of the brush holder and brushes removed from the machine.

Referring to the drawing in detail, where in similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the body of a bolting machine of the ordinary construction suitably mounted for reciprocatory movement transmitted thereto through suitable connections (not shown) with a motor or the like. The usual bolting cloth 6 is se cured over the upper end of the body 5 of the bolting machine.

A pair of spaced beams 7 are suitably secured longitudinally within the bolting machine underneath the bolting cloth 6 and are provided on their adjacent faces adjacent the upper edge with channels 8 slidably receiving the oppositely directed flanges 9 formed at the base of the brush holder 10.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Serial No. 854,941.

The upper portion of the brush holder is triangular in cross section as illustrated in Fig. 3 providing a pair of oppositely inclined top faces 11 for deflecting the flour sifted through the bolting cloth 6.

The intermediate portion of the holder 10 is reduced at 12 and slidably mounted between the upper portions of the beams 7. The opposite ends of the top edge of the holder are cut away to provide recesses in which are secured the heads 13 carrying bristles 14 engaging the upper face of the bolting cloth 6 and extending the entire distance across the latter.

A recess 16 is formed centrally in the under face of the holder 10 and receives a member 17 pivotally supported therein on a pin 18. The lower end of the member 17 is curved inwardly to provide teeth 19 on opposite sides thereof. A. plurality of spaced bolts or pins 20 are secured in horizontal alinement between the lower portions of the beams 7 and are arranged centrally with relation to the end of the beams whereby when the holder 10 moves to one end of the machine the pivoted member 17 passes over the pins 20 and drops to a vertical posi tion, as illustrated in Fig. 2. As the holder 10 shifts'longitudinally within the machine owing to the reciprocation of the latter and the beams 7, the pivoted member 17 is carried upon the pins 20, as illustrated in 1. After the holder has started to move in one direction longitudinally of the machine and the pivoted member 17 is engaged upon the pins 20 it is impossible for the holder to move in the opposite direction until it travels to the end of the machine toward which it initially started. The brushes 14 carried by the holder 10 are thus drawn from one end. to the opposite end of the machine during the operation thereof engaging and efiectively cleaning the cloth 6.

What we claim is 1. In combination, a reciprocatory bolting machine including a body and a cloth secured therein, a pair of beams arranged in spaced relation in said body, a brush holder slidable longitudinally between said beams having oppositely inclined top faces, brushes secured at the opposite ends of said holder. and means for controlling the direction of travel of said brush holder including a gravity actuated pawl and a plurality of spaced rods secured in said beams.

2. In combination, a bolting machine inof said cloth, and a double toothed pawl pivoted in the lower portion of said brush holder to control the direction of travel of 15 said holder.

In testimony whereof we afiix our signatures in presence of two witnesses.
